Overview
The S Pack DQ3 Purification Cartridge is a high-integrity, single-use modular component engineered for integration into ultra-pure water (UPW) distribution systems and point-of-use purification loops. Designed in accordance with ISO 3696:1987 (Grade 1 water specifications) and aligned with ASTM D1193-2020 Type I water requirements, the DQ3 cartridge delivers consistent removal of residual ions, organic compounds, colloidal silica, and sub-micron particulates from pre-polished water streams. Its core architecture employs a layered media configuration—comprising mixed-bed ion exchange resins, catalytic activated carbon, and a final 0.1 µm absolute-rated polyethersulfone (PES) membrane—ensuring stable resistivity ≥18.2 MΩ·cm at 25 °C and total organic carbon (TOC) levels <1 ppb under validated flow conditions. Unlike traditional multi-stage polishing units, the DQ3 operates as a drop-in replacement module compatible with standard 10-inch sanitary housing interfaces (DIN 11851 or SMS 1144), minimizing system downtime during maintenance cycles.
Key Features
- Modular design with standardized 10-inch (254 mm) length and 63.5 mm outer diameter, compliant with ANSI/ASME B16.5 Class 150 flange dimensions for direct integration into existing UPW skids.
- Pre-validated performance: Each batch undergoes conductivity mapping, TOC challenge testing, and endotoxin screening per USP and , with full Certificate of Conformance (CoC) and Certificates of Analysis (CoA) supplied.
- Low extractables profile: Media matrix certified to meet EP 2.2.59 and JP XVII limits for non-volatile residue (<0.1 mg/unit) and heavy metals (<0.1 ppm).
- Pressure-rated housing interface: Supports continuous operation up to 6 bar (87 psi) at 25 °C with thermal cycling stability from 5–40 °C.
- Integrated RFID tag (ISO 15693 compliant) for automated lot traceability, service life logging, and integration with facility SCADA or CMMS platforms.
Sample Compatibility & Compliance
The DQ3 cartridge is intended for use with feed water meeting ASTM D1193 Type II or ISO 3696 Grade 2 specifications (resistivity ≥1 MΩ·cm, TOC <50 ppb). It is not designed for raw municipal feed or seawater desalination effluent. Regulatory alignment includes compliance with GMP Annex 1 (2022) requirements for water system component qualification, FDA 21 CFR Part 211 Subpart J (Water Systems), and EU GMP Guide Chapter 4 (Water for Pharmaceutical Use). All materials of construction—housing polypropylene (PP), O-rings EPDM, and internal wetted surfaces—are USP Class VI certified and compliant with EC 1935/2004 for food contact applications.
Software & Data Management
While the DQ3 itself is a passive hardware component, its embedded RFID enables bidirectional data exchange with Deepflow’s AquaTrack™ Asset Manager software (v3.2+). This platform supports electronic batch records, real-time usage tracking based on cumulative flow volume and pressure differential trends, and automatic alerting when approaching nominal service life (typically 6–12 months depending on inlet water quality and throughput). Audit trails comply with FDA 21 CFR Part 11 requirements, including user authentication, electronic signatures, and immutable record retention for ≥25 years. Integration with LIMS via HL7 v2.5 or OPC UA is supported through optional middleware modules.
Applications
- Final polishing stage in semiconductor fab UPW loops requiring particle counts <1 particle/mL @ ≥0.05 µm (per SEMI F63-0218).
- Pharmaceutical water-for-injection (WFI) distribution loop guard filtration in accordance with EU Annex 1 and WHO TRS 970.
- Research-grade water supply for ICP-MS, LC-MS/MS, and atomic absorption spectroscopy where low metal leachables (<0.01 ppb Ni, Cu, Fe) are critical.
- Cell culture media preparation environments requiring endotoxin-free output (<0.001 EU/mL) verified by kinetic chromogenic LAL assay.
- Calibration lab reference water generation for traceable conductivity and pH standards.
FAQ
What is the recommended maximum operating flow rate for the DQ3 cartridge?
The validated linear velocity limit is 0.15 m/s across the membrane surface, corresponding to ≤12 L/min at 25 °C for standard 10-inch housings. Exceeding this may compromise TOC adsorption kinetics and increase particle shedding risk.
Can the DQ3 be sterilized in place (SIP) using saturated steam?
No. The PES membrane and ion exchange resins are not SIP-compatible. Autoclaving or steam exposure above 60 °C will irreversibly degrade performance. Sterile installation requires aseptic housing assembly under ISO 5 conditions.
Is the RFID tag readable through stainless-steel housing enclosures?
Yes—RFID interrogation remains reliable through non-ferromagnetic housings (e.g., 316L SS) up to 25 mm wall thickness, provided no ferrous shielding or high-frequency EMI sources are present within 30 cm.
Does Deepflow provide PQ protocol templates for DQ3 qualification?
Yes. A complete IQ/OQ/PQ validation package—including test scripts for pressure drop verification, flow calibration, and conductivity/TOC challenge protocols—is available under NDA upon request.
How is end-of-life determined for the DQ3 cartridge?
End-of-life is defined by either cumulative throughput exceeding 12,000 L (typical), ΔP > 2.5 bar at rated flow, or real-time conductivity rise >0.05 µS/cm over baseline—whichever occurs first. RFID-based usage counters support predictive replacement scheduling.
